GMTIFS a near-infrared Integral-Field Spectrograph instrument is being designed for the Giant Magellan Telescope. This instrument contains precision mechanisms that must operate in a cryogenic vacuum. The positioning control system requires high precession resolvers that can operate under these challenging operating conditions. A prototype mechanism has been manufactured to validate a capacitive displacement sensor-based resolver system. This poster will report on the performance results of the capacitive displacement sensors and the resolver system under representative cryogenic vacuum conditions expected within the final GMTIFS cryostat.
